HENRY CASEBOLT, OF SAN FRANCISCO, CALIFORNIA.

SPECIFICATION forming part of Letters Patent No. 249,300, dated November 8, 1881. `Application tiled September 24, 1881. (No model.)

To all whom it may concern.:

Be it known that I, HENRY CAsnBoL'r, of the city of San Francisco and State of California, have invented a new and Improved Tunnel-'Frame for the Construction of Cable- Ways; and I hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in Which- Figure lis a side elevation of the frame. Fig. 2 is a plan of the same. Figs. 3 and et are details to be referred to.

The object of my' invention is to provide a cheap and substantial yoke and frame-work for the tunnel and track of underground cableroads; and my invention consists in certain details of construction and combinations of angle-iron and dat iron bars, as hereinafter fullydescribed and specically claimed,

In order that those skilled in the art may make and use `my.invention,.I will proceed to Vdescribe the manner in which I have carried it out.

In the said drawings, the yoke A is formed of two bars of angle-iron, N N', having their hat faces toward the tunnel, as seen in Fig. 3, and between these two bars of angle-iron are faces up, and having an intervening dat iron bar coincidentin shape with an angle-iron supporting-bracket, Gr, for supporting the angleiron slot-ironH. n

'Ihe support for the slot-iron is made of two bars of angleiron, I K, (seen in plan, Fig. 2,) the dat faces of the said bars lying against the `upturnedflat faces of the bindin g-bars E F, and

between them is the Hat iron bar h, which terminates at such a point as to allow the pas- `wardly-projecting ribs of the angle-iron.

sage ot' bolt i between the angle-iron bars I K, the nut k resting on the supports for the slotiron, and the head l resting against thedown- Between the ends of angle-iron bars E F are boltedflat bars L by means ot' bolts m, and then the Vsaid bars L are twisted (see Fig. 2) into a plano at right angles to the position ot' the ends, and, passing to the next track, are secured in likev manner, so as to bind the double tracks securely together.

In bending the angle-iron to form the yoke the dependent web at the lowerI endot' the bight may be out out in a V-shaped cut., so as 4 to prevent any possible breakage or fracture when the iron is bent. t

The brace and counter-brace, made of flat bar-iron, with the ends inserted between the angle-iron hars and bolted, secure the entire frame-Work so rigidly that there is perceptibl y no yield or give to it whatever.

In constructing the tunnel for thccable-road the edges of the sheet-iron or other sheathing are laid against the exterior of the faces of the angle-iron yokes.

It' desired, the lower portion of the tunnel may be given a decided pitch b v means ot' a sheet-metal gutter. (Shown in dottedlines in Fig. l y

Having thus described my invention, what I claim as new, and desire to sec-ure by Letters Patent, is

The combined truss, and tunnell for under ground cable-ways, consisting ofthe an gle-iron yoke N N', the angle-iron binding-bars E F, the angle-iron supports I K, and .the fiat iron truss-bars, all constructed and operated as described.

In testimony whereof set my hand this Witnesses:
